Due to unfortunate circumstances (me dropping the laptop) I have now ended up with a half broken laptop that has a broken screen and a dying battery. I could repair it, however, I don’t wanna bother as I’m very likely gonna be getting a new one soon.
The laptop itself still works fine, however the broken screen and dying battery make it pretty much useless as a laptop and I already have a home lab NAS thing, so I’m kinda out of ideas on what to do with it. Any ideas?
Here are the specs:
CPU: i5-8300h
GPU: intel HD830/GTX1050ti
RAM: 16GB
Storage: 128GB SSD
Remove the battery, take the motherboard out of the case. Plug the motherboard in, and voila you have a larger and more powerful raspberry pi. You could use it as a second node for control, management, observation purposes, etc.
Great suggestion, but I’m not entirely sure it’s 100% possible on all models? Some models are built so that it won’t turn on without a battery installed (much like phones) and that the power has to pass through the battery before it reaches the motherboard.
I believe that scenario would take much more knowledge of electricity plus some soldering skills to bypass the battery. They gave specs, but not make and model. I don’t trust companies like HP to not take the route that requires you to send it in to them for servicing.
It does work without the battery and the model is: dell G3 3579, I just didn’t think the model was that important to mention.
95% of the time the exact model isn’t super important, nowhere near as important as specifications, but when it comes to the physical build like whether it can run without the battery, it can be useful to know.
Why remove the battery when it is a perfectly working built in UPS?
Because over time the battery degrades, swells, and becomes a fire risk.
Keeping it only 80% charged can help mitigate it but not fully.
That is largely a myth and in my experience never happens with higher quality laptop batteries. But yes limiting charge doesn’t hurt if it is only used as a UPS anyways.
What part is the myth?
Which batteries are “high quality”?
Cause it happens… Pretty regularly if you’re not limiting charging. The older the battery the more likely.
This isn’t something you should fuck around with either: if it pops it’ll burn too hot to extinguish and could take out your house.
Not a myth. Better batteries might have better safety measures, but none is inmune. It might not have happened to you but I’ve seen it happen in several high end/expensive brands already.
It will be a really bad UPS at best
Because it is a safety issue and the battery isn’t designed for that anyway. A UPS is designed to stay charged for a long period of time and laptop is not.
Make sure you have a cooling solution…
you can keep the fan and heatsink on the board
If you remove the battery it will either A not work or B run extremely slowly. Always have a functional battery in your laptops.
Ideally find a way to limit the charge of the battery. But if you can’t nuking your battery is better than running at 800mhz or whatever your lowest clock speed is.
I’ve run laptops before without batteries a few times and never had issues, is there a reason for the slowdown?
Power consumption. Especially with turbo boost power consumption can easily spike well above what the power brick can deliver, so the battery is used like a capacitor. Or shit even without the spikes chargers can’t keep up. My laptop will actually discharge under full load with the full 240 watt charger.
It’s not normally an issue on REALLY low end devices (sub core i, like pentiums or atoms), but anything high end will reduce it’s power consumption without a batter installed.
That’s not something that should ever happen on most devices. If your battery is discharging under load you likely have a faulty device.
There’s nothing wrong with the device, Lenovo has confirmed this, and both motherboards my laptop has had have the same “problem”. This isn’t my only machine like this either, 16" Intel MacBook Pros are also known to discharge under full load, but that’s because they’re limited to 100 watt USB C.
There’s a reason why those devices run at minimum clock speeds when their battery is sub 5%.
That’s a terrible design then. I would never want a device that would do that
Well I hope you don’t like ThinkPads…
I don’t but that’s beside the point
My Lenovo P1 with an i7 and a Nvidia 4900 and a 230W adapter is wondering what you’re talking about.
Interesting, never had that happen to me, but then perhaps you are using a laptop with a dgpu? I have not been. My laptop generally consumes 4w at idle and up to 15w under load, so I don’t see this ever outpacing the 60w charger. The CPUs with the highest tdp are only around 100w anyway right? And in that case the laptop comes with a higher wattage charger. But you’re right I guess it could happen depending on the hardware, never personally seen it however.
It even happens with power efficient devices. All Macbooks will run at their lowest clock speed with a dead/low battery (even my M1), My Thinkpad T14 with an ULV CPU and it’s odd. It tries to limit total system power to around 25 watts, even though I have a 100 watt power supply connected. My theory is that since 30 watts is the lowest power supply it will run off of it’s trying to keep that 5 watt buffer. Unfortunately that means my CPU runs at 800mhz doing anything but idling. Laptops with dGPUs often just wont work at all, or are so far limited they’re unusable.
Some older laptops like my Thinkpad X220 will run at 800mhz on a 65 watt charger, but on a 90 watt charger it will run at full speed. But unfortunately in the days of USB C that makes things a lot more difficult.
